An Etymological Dictionary of the German Language/Rotz

by Friedrich Kluge

Rotz, m., ‘mucus, snot,’ from the equiv. MidHG. roz, rotz, OHG. roz, earlier hroz, m. and n., formed from a Teut. root hrū̆t (Aryan krud); comp. OHG. rûȥan, AS. hrûtan, ‘to snore, snort,’ OIc. hrjóta. It can scarcely be compared with Gr. κόρυζα, ‘cold, catarrh.’
